[QUOTE="Catbrain, post: 2952994, member: 127536"] I loaded those about 10 years ago. I THINK i remember using new brass. But I looked at the case heads-- and on the other in the same box- most have a little bevel on the outer edge of the rim. Like a little wear or maybe where they hit the action on the way out. So it could be just a bad case. I loaded 10 solids and 10 hornady interlocks with that brass. I might try shooting 2 or 3 of the interlocks just to see what the brass does. I talked to a Tech at Hornady and he thought the sharp edges of the relief grooves could have tried to grab the case neck. But it doesnt look like that to me--- as an artifact---- there are two vert. cracks in the neck. Each of the cracks-- at it's top and bottom-- there is a little round hole--- all most like the hole was gas cut. What is that telling me ? The dies are rcbs--- and I just dont like them. I think I will order a set of lee dies withe the collet crimper. im used to them and have had good luck using them. Never had this kind of crap before----- as an aside---- I have seen brand new factory brass exhibit a lind of slot down the side like the metal got a pleat or fold in it during one of the forming steps--- then it went through a couple more pulls and the defect area got ironed flat--- but still there. i have a split-ball type internal hole gauge-- I may try to directly measure the neck area inside the chamber. see what I see. i compared the inner and outer diameters to some of my 308 brass and got just about all the same measurements. I just don't like how that rcbs die is working. i don't think I trust it. [/QUOTE]
